Be the company or organisation’s size is small or big, there is a need for network security solutions to some degree, so as to protect it from any kind of cyber threats.

Now we shall have a look at these in slight detail.

  • Physical Network Security:
    Physical Security controls are designed in a way that prevents unauthorised personnel from gaining physical access to network components like routers, cabling cupboards and so on. Controlled access, such as locks, biometric authentication and other devices is almost unavoidable and must be there. 
  • Technical Network Security:
    Technical Security Controls protect data stored over on the network. The protection that is being facilitated is twofold. It needs to protect data and systems from unauthorised personnel, and it also needs to provide protection.
  • Administrative Network Security:
    Administrative Security has control which comprises of security policies and processes which are potent in controlling user behaviour, including how even users are authenticated, their level of access and how IT staff members implement changes to their infrastructure.

Types of Network Security:

1. Network Access Control:

To be able to ensure that attackers can not infiltrate other networks, comprehensive access control policies are needed to be in a better place for both users and devices. Network access control (NAC) should be set at the most granular level. An instance of the same is if we grant more or full access to administrators of the network, but we deny giving access to specific confidential folders, or not letting certain devices from joining the network.

2. Antivirus and Antimalware Software:

Antivirus and antimalware software are competent in protecting any organization from a range of malicious software, inclusive of viruses, ransomware, worms and trojans. The best software also scans files upon entry to the network but continuously scans and tracks files.

3. Firewall Protection:

Firewalls act as a barrier between the not-so-trustworthy external networks and the trusted internal network. Administrators configure a set of defined rules that block or permit traffic onto the network.

4. Virtual Private Networks:

Virtual Private Networks (VPNs) create a connection to the network from another endpoint or site. For example, users that are working from home would connect to the organisation’s network over a VPN. Data between certain two endpoints is encrypted and the user would need to authenticate to further allow communication with their device and also the network.

5. Network Security and businesses and consumers:

Network security is always of prime priority for any organization that performs and works with networked data and systems. In addition to protecting assets and the integrity of data from external exploits. Network security can also manage network traffic very efficiently, enhance network performance and ensure secure data sharing between employees and other data sources.
